CROSS REFERENCE TO RELATED APPLICATION
 This application claims the benefit of priority under 35 U.S.C. §119(e) from U.S. Provisional Application Ser. No. 61/428,347, filed Dec. 30, 2010, the entire contents of which is hereby incorporated by reference.
FIELD OF THE INVENTION
 The present invention relates to mascara compositions comprising at least one micronized wax. The mascara compositions have beneficial cosmetic properties including comfort upon application and improved volumizing and/or shine properties.
DISCUSSION OF THE BACKGROUND
 Mascaras are generally prepared on the basis of two types of formulations: aqueous mascaras referred to as cream mascaras, in the form of a dispersion of waxes in water, and anhydrous or low-water-content mascaras, referred to as water-resistant mascaras (referred to as "waterproof"), in the form of dispersions of waxes in organic solvents.
 Aqueous mascaras mainly contain a surfactant system, for example based on triethanolamine stearate, which makes it possible to obtain a stable dispersion of particles of wax agglomerated in an aqueous phase. This system plays an important part in the obtaining of such a dispersion, in particular at the interface in the interactions between particles of wax.
 However, the mascaras described above have the disadvantages of, among other things, being dry, having poor flexibility and/or having poor consistency.
 There is thus a need to develop a cosmetic composition, in particular for making up the eyelashes, making it possible to obtain a smooth and homogeneous deposit on the eyelashes, while exhibiting a consistency that is easy to work after application, which has improved volumizing, curling and/or shine properties.
SUMMARY OF THE INVENTION
 The present invention relates to compositions for eyelashes and/or eyebrows comprising at least one micronized. Preferably, the composition is a mascara composition. Preferably, the composition is anhydrous.
 The present invention also relates to methods of treating, caring for and/or making up eyelashes and/or eyebrows by applying compositions of the present invention to eyelashes and/or eyebrows in an amount sufficient to treat, care for and/or make up the eyelashes and/or eyebrows. Preferably, the composition is a mascara composition. Preferably, the composition is anhydrous.
 The present invention also relates to methods of improving the volumizing and/or shine properties of a composition for eyelashes and/or eyebrows, comprising adding to the composition at least one micronized wax. Preferably, the composition is a mascara composition. Preferably, the composition is anhydrous.
 It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention.
DETAILED DESCRIPTION OF THE INVENTION
 As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures/combinations.
 Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about," meaning within 10% to 15% of the indicated number.
 "Film former" or "film forming agent" as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.
 "Anhydrous" means the compositions contain less than 1% water. Preferably, the compositions of the present invention comprising the at least one micronized wax contain no water.
 "Tackiness" as used herein refers to the adhesion between two substances. For example, the more tackiness there is between two substances, the more adhesion there is between the substances. To quantify "tackiness," it is useful to determine the "work of adhesion" as defined by IUPAC associated with the two substances. Generally speaking, the work of adhesion measures the amount of work necessary to separate two substances. Thus, the greater the work of adhesion associated with two substances, the greater the adhesion there is between the substances, meaning the greater the tackiness is between the two substances.
 Work of adhesion and, thus, tackiness, can be quantified using acceptable techniques and methods generally used to measure adhesion, and is typically reported in units of force time (for example, gram seconds ("g s")). For example, the TA-XT2 from Stable Micro Systems, Ltd. can be used to determine adhesion following the procedures set forth in the TA-XT2 Application Study (ref: MATI/PO.25), revised January 2000, the entire contents of which are hereby incorporated by reference. According to this method, desirable values for work of adhesion for substantially non-tacky substances include less than about 0.5 g s, less than about 0.4 g s, less than about 0.3 g s and less than about 0.2 g s. As known in the art, other similar methods can be used on other similar analytical devices to determine adhesion.
 "Waterproof" as used herein refers to the ability to repel water and permanence with respect to water. Waterproof properties may be evaluated by any method known in the art for evaluating such properties. For example, a mascara composition may be applied to false eyelashes, which may then be placed in water for a certain amount of time, such as, for example, 20 minutes. Upon expiration of the pre-ascertained amount of time, the false eyelashes may be removed from the water and passed over a material, such as, for example, a sheet of paper. The extent of residue left on the material may then be evaluated and compared with other compositions, such as, for example, commercially available compositions. Similarly, for example, a composition may be applied to skin, and the skin may be submerged in water for a certain amount of time. The amount of composition remaining on the skin after the pre-ascertained amount of time may then be evaluated and compared. For example, a composition may be waterproof if a majority of the product is left on the wearer, e.g., eyelashes. In a preferred embodiment of the present invention, little or no composition is transferred from the wearer.
 "Substituted" as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.
 "Volatile", as used herein, means having a flash point of less than about 100° C.
 "Non-volatile", as used herein, means having a flash point of greater than about 100° C.
 The compositions and methods of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful.

 Thermoplastic elastomers useful in the present invention include block copolymers e.g., di-block, tri-block, multi-block, radial and star block copolymers, and mixtures and blends thereof. A di-block thermoplastic elastomer is usually defined as an A-B type or a hard segment (A) followed by a soft segment (B) in sequence. A tri-block is usually defined as an A-B-A type copolymer or a ratio of one hard, one soft, and one hard segment. Multi-block or radial block or star block thermoplastic elastomers usually contain any combination of hard and soft segments, provided that the elastomers possess both hard and soft characteristics.
 In preferred embodiments, the thermoplastic elastomer of the present invention may be chosen from the class of Kraton® rubbers (Shell Chemical Company) or from similar thermoplastic elastomers. Kraton® rubbers are thermoplastic elastomers in which the polymer chains comprise a di-block, tri-block, multi-block or radial or star block configuration or numerous mixtures thereof. The Kraton® tri-block rubbers have polystyrene (hard) segments on each end of a rubber (soft) segment, while the Kraton® di-block rubbers have a polystyrene (hard) segment attached to a rubber (soft) segment. The Kraton® radial or star configuration may be a four-point or other multipoint star made of rubber with a polystyrene segment attached to each end of a rubber segment. The configuration of each of the Kraton® rubbers forms separate polystyrene and rubber domains.
 Each molecule of Kraton® rubber is said to comprise block segments of styrene monomer units and rubber monomer and/or co-monomer units. The most common structure for the Kraton® triblock copolymer is the linear A-B-A block type styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylenepropylene-styrene, or styrene-ethylenebutylene-styrene. The Kraton® di-block is preferably the AB block type such as styrene-ethylenepropylene, styrene-ethylenebutylene, styrene-butadiene, or styrene-isoprene. The Kraton® rubber configuration is well known in the art and any block copolymer elastomer with a similar configuration is within the practice of the invention. Other block copolymers are sold under the tradename Septon (which represent elastomers known as SEEPS, sold by Kurary, Co., Ltd) and those sold by Exxon Dow under the tradename Vector®.
 Other thermoplastic elastomers useful in the present invention include those block copolymer elastomers comprising a styrene-butylene/ethylene-styrene copolymer (tri-block), an ethylene/propylene-styrene copolymer (radial or star block) or a mixture or blend of the two. (Some manufacturers refer to block copolymers as hydrogenated block copolymers, e.g. hydrogenated styrene-butylene/ethylene-styrene copolymer (tri-block)).

 Suitable fibers include, but are not limited to, fibers which enable improvement of the lengthening effect. "Fiber" should be understood to mean an object of length L and diameter D such that L is much greater than D, D being the diameter of the circle in which the cross-section of the fibre is inscribed. In particular, the L/D ratio (or form factor) is selected in the band ranging from 3.5 to 2500, in particular from 5 to 500, and more particularly from 5 to 150. The fibers utilisable in the composition of the invention can be fibers of synthetic or natural origin, mineral or organic. They can be short or long, unitary or structured, for example, braided, hollow or full. They can be of any shape and in particular of circular or polygonal cross-section (square, hexagonal or octagonal) depending on the specific application envisaged. In particular, their ends are blunted and/or polished to avoid injury. They can be rigid or non-rigid fibers. They can be of synthetic or natural origin, mineral or organic. They can be surface treated or not, coated or not, and colored or not.

In accordance with these preceding preferred embodiments, the compositions of the present invention are applied topically to the desired area in an amount sufficient to treat, care for and/or enhance the appearance of the keratinous material. The compositions may be applied to the desired area as needed, preferably once or twice daily, more preferably once daily and then preferably allowed to dry before subjecting to contact such as with clothing or other objects (for example, a glass or a topcoat). Preferably, the composition is allowed to dry for about 1 minute or less, more preferably for about 45 seconds or less. The composition is preferably applied to the desired area that is dry or has been dried prior to application, or to which a basecoat has been previously applied.
 According to a preferred embodiment of the present invention, compositions having improved cosmetic properties such as, for example, improved feel upon application (for example, texture, reduced drag or tackiness), increased volume properties and/or increased shine wear properties are provided.
 According to other embodiments of the present invention, methods of improving the volumizing and/or shine properties of a composition, comprising adding at least one micronized wax and at least one water-soluble wax to the composition are provided.
